Central churning equipment

Abstract

The invention provides central churning equipment. The equipment comprises a stirring tank and a stirring system; the stirring system comprises a stirring shaft, a flow guiding device and a power mechanism; the flow guiding device comprises a flow guiding cylinder and a supporting member, and the flow guiding cylinder is installed on the supporting member; the power mechanism comprises a power component and a power machine frame, and the power component is installed on the power machine frame; the stirring shaft is circumferentially and fixedly connected with a power output shaft included in the power component; the stirring shaft reaches the flow guiding cylinder in a length extension direction; and the stirring tank comprises an upper seal head component, assembly connection holes are formed in the upper seal head component, the supporting member runs through the assembly connection holes in a length extension direction, and the supporting member is connected with the upper seal headcomponent through seal connection pieces. According to the equipment provided by the invention, the stirring system can be installed in the stirring tank and forms a separate fluid ascending channel,so that circumferential flow spreading of the fluid when the fluid is conveyed upwards is reduced, the bottom raw material can be efficiently transported and re-stirred, and the stirring efficiency is improved.

Description

technical field [0001] The invention relates to the field of stirring, in particular to a central churning device. Background technique [0002] The agitator is a device for forced convection and uniform mixing of liquid and gaseous media. The type, size and speed of the stirrer have an effect on the distribution of the stirring power between the bulk flow and the turbulent pulsations. Generally speaking, the power distribution of the turbine agitator is favorable for turbulent flow fluctuations, while the propeller agitator is favorable for the bulk flow. For the same type of agitator, under the condition of the same power consumption, the agitator with large diameter and low rotation speed mainly consumes power in the overall flow, which is conducive to macroscopic mixing. [0003] For the raw materials at the bottom of the mixing tank, in order to make them evenly mixed, two methods are usually used in the prior art: one is to erect a pipeline at the bottom of the mixin...

AI Technical Summary

Problems solved by technology

In addition, the stirring shaft itself will have a small movement in the radial direction due to the influence of the eddy current, which will affect the assembly and sealing between the stirrer and the stirring tank. At present, there is no good structure to solve the above problems.
